Question

I am trying to use NSJSONSerialization to serialize the data returned from stack overflow API, but it is not working as intended 🙁

I am using code as below :

NSURL *apiURL = [NSURL URLWithString:@"http://api.stackoverflow.com/1.1/questions?tagged=objective-c&pagesize=30"];

NSError *error = nil;

// First option - failed
NSInputStream *inputStream = [NSInputStream inputStreamWithURL:apiURL]; // returning nil
id jsonFound1 = [NSJSONSerialization JSONObjectWithStream:inputStream options:NSJSONReadingMutableContainers error:&error];

// Second option - failed
NSData *jsonData = [NSData dataWithContentsOfURL:apiURL]; // returning correct value, verified after converting it to NSString

id jsonFound2 = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&error];  // returning nil

I am trying the above code in Xcode 4.2 for iOS5 and I am getting (null) for inputStream and for jsonFound2.

Earlier I was doing it through SBJSON and it was working correctly.

Can anyone suggest me if I am doing anything wrong or missing anything?

First option does not work because it supports only file url (thanks to David for pointing).

Second option works fine for remote urls.
